What is this

A rebuild is the alteration of an existing building that changes its volume or load-bearing structures — unlike simple repairs. It requires a building permit, and the case goes through the same BIS stages as a new build.

A neighbouring house's rebuild can mean lengthy construction works, noise and a changed look of the surroundings. For a buyer it matters as much as a new build next door — and is often less noticeable, because the building is already standing.

Frequently Asked Questions / FAQ

How does a rebuild differ from repairs?
A rebuild changes the building's volume or load-bearing structures and requires a building permit. Simple repairs that do not touch the structures do not require one.
How do I find out whether the neighbours' house is being rebuilt?
Open the rebuild layer on the map and look around the neighbourhood — every registered rebuild case is shown in its place with its stage.
What do the colours mean?
They show the stage: design, conditions for starting works, construction works or commissioning.
